In accompanying drawing: 1, chilled water import; 2, adventitia Quench water cavity; 3, inner membrance Quench water cavity; 4, inward turning pendular ring; 5, adventitia covers pendular ring; 6, downtake; 7, water hole; 8, diversion trench.
Embodiment
As shown in Figure 1, chilling ring device of the present invention, mainly covers the parts such as pendular ring 5, downtake 6, water hole 7 by chilled water import 1, adventitia Quench water cavity 2, inner membrance Quench water cavity 3, inward turning pendular ring 4, adventitia and forms.It is characterized in that: chilled water is entered adventitia Quench water cavity 2 rotation rapidly in chamber along 45 ° of inclination angles by chilled water import 1.Quench moisture two-way: the annular space that a road chilled water is covered between pendular ring 5 and downtake 6 by adventitia forms in downtake outside the protection moisture film declining; The water hole 7 of separately leading up to enters inner membrance Quench water cavity 3; form protection moisture film by the annular space between inward turning pendular ring 4 and downtake 6 at downtake 6 inwalls again; due to the cyclonic action of inward turning pendular ring 4, the protection moisture film of downtake 6 inwalls flows downward from the horizontal by 65 ° of rotations.Inside and outside downtake 6, all form moisture film, increased heat transfer effect, strengthened the provide protection to downtake.
As shown in Figure 2, chilled water import 1 and adventitia Quench water cavity 2 in the horizontal direction with all inclination angles at 45 ° of vertical direction.Chilled water import 1 is 45 degree at the angle of perpendicular projection and adventitia Quench water cavity 2, and chilled water import 1 angle between projection and adventitia Quench water cavity 2 tangent lines of adventitia Quench water cavity 2 connecting portions (the chilled water import 1 with) on horizontal plane is 45 degree.
As shown in Figure 4, it is characterized in that adventitia covers pendular ring 5 and forms annular space with downtake 6, annular space size 5～8mm, is preferably 6mm.Adventitia covers pendular ring 5 height 50～100mm, and preferred heights is 60mm.Water hole 7 size Ф 33mm, amount to 24, by circumference uniform distribution.
As shown in Figure 4, described inward turning pendular ring 4 forms annular space with downtake 6, and annular space size 2～5mm, is preferably 2mm.Described inward turning pendular ring 4 thickness are not less than 15mm, and between 15～25mm, the present invention is preferably 15mm.
As shown in Figure 3, it is characterized in that the close end face of described inward turning pendular ring 4 and downtake 6 is provided with diversion trench 8, diversion trench 8 size 8 × 8mm, spacing 15～30mm is uniform, and the present invention is preferably 15mm.As shown in Figure 3, it is characterized in that described diversion trench 8 angles of inclination are between 0 °～90 °, the present invention is preferably by 65 ° of settings of horizontal direction.
Be described below below in conjunction with 1～4 pair of specific works process of the present invention of accompanying drawing:
Chilled water enters adventitia Quench water cavity 2 by chilled water import 1, and chilled water import 1 all adopts 45 ° of inclination angles in vertical and horizontal direction.As shown in Figure 2, the inclination angle design of 45 ° can make to enter the chilled water rotation rapidly in chamber in adventitia Quench water cavity 2, prevent that chilled water is at the grey dirt deposition of adventitia chilled water chamber 2 interior formation, simultaneously the fast rotational of chilled water has also been accelerated chilled water in cavity and the thermal exchange of vapourizing furnace burner hearth, the operating temperature that can further reduce Failure of Gasifier Conical Bottom, has prevented the generation at local dead angle.
Chilled water is point two-way in adventitia chilled water chamber.The gap that the adventitia of leading up to covers 6mm between pendular ring 5 and downtake 6 forms protection moisture film to dirty at downtake outer wall.Old-fashioned chilling ring, owing to there is no the design of outer moisture film, easily causes downtake 6 outer walls directly to contact with the synthetic gas of high temperature, thereby causes the high temperature modification of downtake 6.The design of outer wall protection moisture film is played protection downtake 6 and is increased the effect of heat transfer effect.
In original chilling ring structure, chilled water forms moisture film by the gap between Quench water cavity bottom side steel plate and downtake 6, due to the pressure release effect of chilled water, forms splash after being easy to cause chilled water to pass gap.In order better to form outer wall protection moisture film; prevent the splash of chilled water, as shown in Figure 4, be provided with the highly adventitia for 60mm in downtake 6 outsides and cover pendular ring 5; cover the effect that covers of pendular ring 5 by adventitia, be conducive to form uniform moisture film at the outer wall of downtake 6.
Another road chilled water enters inner membrance Quench water cavity 3 by the water hole 7 of 24 diameter Ф 33, by the diversion trench 8 between inward turning pendular ring 4 and downtake 6 and the gap of 2mm, chilled water, forms the moisture film of rotation along downtake 6 inwall rotations downwards at downtake inwall.
As shown in Figure 3, inward turning pendular ring 4 is provided with the diversion trench 8 from the horizontal by the 8 × 8mm of 65 °, and interval 15mm is uniform, and due to the cyclonic action of inward turning pendular ring 4, the protection moisture film of downtake 6 inwalls flows downward from the horizontal by 65 ° of rotations.In order to strengthen the guide functions of inward turning pendular ring 4, the height of inward turning pendular ring 4 is preferably 200mm, chilled water from inward turning pendular ring 4 flows out because inertia effect continues to flow downward along the rotation of downtake inwall.The souring of high-temperature synthesis gas is to destroy the major reason of downtake moisture film, in vapourizing furnace actual motion, often encounter because downtake 6 moisture films destroy the accident that causes downtake 6 temperature risings to cause downtake 6 high temperature modification, had a strong impact on the long-period stable operation of vapourizing furnace.The downtake moisture film destroying due to the souring of high-temperature synthesis gas has been repaired in the turning effort of chilled water automatically, has guaranteed the normal operation of downtake 6.
